In the UK, I often hear the phrase "Climb level XXX, when instructed by ACC climb to level YYY". No problem - good idea telling people what they can expext (so we may advise other requested level
on initial contact with ACC).
However, it appears that ATCO's are very keen on having a readback of the last part of the message. Why? It is NOT a claerance, advisory only. I would think it simpler and thus safer to read-back only cleared level, not what to ecpect later on.
Or is there indeed a good reason???
